What is 543 ÷ 5?

• A. 108 R 2
• B. 109 R 3
• C. 107 R 3
• D. 108 R 3

Answer: (D)

Dividing with a remainder means finding how many whole times the divisor fits into the dividend and what is left over. To verify, multiply the divisor by a candidate quotient and see how close you get to the dividend.

For 543 ÷ 5, 5 times 108 is 540. Subtracting gives 543 − 540 = 3, which is smaller than 5, so you can’t fit another whole 5. That means the quotient is 108 and the remainder is 3, since 543 = 5 × 108 + 3.
